Request password on combo box?

Hi,

Is it possible to create a request password on a combo box? Ideally I would like to create a number pad which comes up and prompts the user to enter thier password once they try to edit the data in the combo box?

Thanks

Your best effort is to set the .Enabled property of the combo to False, and stick a button next to it to enabled editing. The button click can do the request for the password, and if correct, enable the combo.

Ive just tried that and it doesnt work - it greys out the combo box but you can still click on the button which switches the combo box and it changes the data :S
